100g mayonnaise (I used Hellman's)

Method

Heat oven to 180C/fan 160C/gas 4. Pour enough water into a small pan to one-third fill it. Bring to the boil, then remove the pan from the heat. Put the chopped chocolate into a large bowl that will fit snugly over the pan without touching the water. Sit the pan over the water (still off the heat) and leave the chocolate to melt slowly for a few mins, stirring occasionally until it has melted evenly. Remove the bowl from the pan, then let the chocolate cool slightly.

Meanwhile, lightly oil and base-line a 19cm square cake tin that is 5cm deep. Combine the flour, cocoa and bicarbonate of soda. Using a wooden spoon, stir both the sugars into the cooled chocolate with the coffee, vanilla and buttermilk. Stir in 1 tbsp warm water. Break and beat in the egg, then stir in the mayonnaise just until smooth and glossy. Sift over the flour and cocoa mix, then gently fold in with a spatula without overmixing.

Pour the mixture into the tin, then gently and evenly spread it into the corners. Bake for 30 mins. When a skewer is inserted into the middle, it should come out with just a few moist crumbs sticking to it. If cooked too long, the mix will dry out; not long enough and it can sink. Leave in the tin until completely cold, then loosen the sides with a round-bladed knife. Turn out onto a board, peel off the lining paper and cut into 12 squares.

Comments, questions and tips

These went down very well indeed! I switched the recipe up a little bit by reducing the sugar by 40g and using 85% dark chocolate to try and make them a little more chocolatey. I also added chocolate chips to one half of the mixture and a handful of frozen raspberries to the other half. Only 4/5 as although they were yummy they weren't quite the best gooey sticky chocolatey brownies I've ever made

Best brownie recipe I've ever tried, and my housemates have now started using mayonnaise for cooking too. These always disappear in half an hour even though I make double the amount suggested here. Great recipe!

Thanks for your question. The answer is yes, you can freeze these brownies. We mark all our freezable recipes with a blue star, you can find this underneath the Facebook and social medial symbols at the top of the recipe. If it's not there, it's not freezable. Hope this helps!

Never made chocolate brownies before, but tried this recipe yesterday, and wanted to add my voice to the rating of 5 stars. It's absolutely divine. Kids love it, tried it with some vanilla ice-cream yesterday, totally delicious! Will be making a couple of batches for a gathering of 23 I'm cooking for at the end of the month, and plan to serve it with ice cream. Thank you for this recipe, I'm sure I'll be making it again and again.........! PS was easy to make too!

Made this in super quick time this evening. The boys were horrified when I put the mayonnaise in and were determined not to like them but unfortunately they did. So I have to share them. Also used light mayo as recommended and used xylitol in place of sugar. They taste delicious.

I made these for the first time yesterday, they were perfect! It did feel weird putting mayonnaise in, but hey ho, they taste goooood!
I didn't have the right size tin but threw caution to the wind and used a 30cm x 9cm x 3cm tin and it worked great. 30 mins was perfect for me.
Although they aren't gooey on the inside, they are so soft and moorish. I will probably put choc chunks or nuts in next time to add a bit of crunch.

Great recipe but made to look a lot more difficult than it actually is with such a long winded explanation of every step!
Instead of 185 of dark chocolate, I used 100g of dark chocolate, 40g of milk chocolate and added a spoonful of golden syrup when I added the chocolate and butter to eggy mousse mix. I also added 1tsp of baking powder to the flour. Instead of 50g of milk and 50g of white choc I used 100g of terrys milk chocolate orange....they were so good, my hubby and his friends were bickering over who would get the last one at a poker night!

Great recipe. A fairly economical brownie, not loads of chocolate and eggs. I did use slightly more cocoa powder [40g] and only had skimmed milk instead of buttermilk. It was a thick mix, not pourable. Result was just moist enough and chocolatey. I will be making these again.

I have just made these and divided into cupckaes and I am waiting to see the result. Slightly worried as in the recipe it says pour into cake tin - my mixture was not purable and I followed it to the letter????!!!!! eeeeeeeeek!

These are absolutely great, and mayonnaise- who'd have thought?! The only thing that would've earned it another star would be that taste you really only get with the stodgy full fat ones! Definitely worth a try if you haven't done this one yet.

Pages

This recipe states 85g chocolate in the ingredient list but comments mention using 150g + in the comments. Has the recipe changed??

Thanks for your question. 85g is the correct quantity.

I'm not sure about using mayonnaise will it make that much difference to the taste without it? Thanks

My advice would be to try it, then decide. I'm confident you won't have anything to worry about!

Hi there. Mayonnaise is just a combination of eggs and oil with some seasoning, it is a way of lowering the fat of the brownies, give it a go you will be surprised how good they are, thanks.

Highly recommend this recipe, I used a milk chocolate bar instead of dark, I had a 110g Cadbury bar so I multiplied other ingredients by 1.3 just to even it out. I also recommend making two batches as it makes 12 small brownies as my family went through them extremely quickly.
